It's hard isn't it? I hate it when people butt in and comment on my own parenting, but if anyone I knew came into contact with babywise, I'd find it extremely difficult to not say something.

Perhaps you could get a book or two (Pinky McKay has a new one just out) and leave it up to her whether she reads it or not. At least you've offered a different perspective than babywise. You could also point out that babies are all different and there is not one routine to fit all.
